| 1 | 董事及高管责任保险:激励还是自利?基于中国上市公司的实证检验显示文摘关于董事及高管责任保险究竟是通过激励董事和高管勤勉、进取,提升公司价值;还是诱发董事及高管的道德风险,助长其自利主义行为,削弱公司价值一直存在争议。论文以2002—2013年沪深A股上市公司为研究样本,采用treatment effect model纠正样本选择性偏差,实证结果表明,董责险可以带来公司价值的显著提升,这一结论对于非金融企业和金融企业同样成立。同时,董责险的价值提升效果会随着制度环境的变化而改变,具体而言,当投资者保护程度较高、公司面临被诉风险较大时,董责险的价值提升效果会更显著。在稳健性检验中,论文使用'董责险相对保额'这一连续变量替代'是否购买董责险'这一虚拟变量,以测度保障程度的变化对公司价值的影响,结论依然稳健。 | 赵杨 John Hu | 2014 | 中国软科学2014,,9: | 56 |
| 2 | A Review of the Functional and Anatomical Default Mode Network in Schizophrenia显示文摘Schizophrenia is a severe mental disorder characterized by impaired perception,delusions,thought disorder,abnormal emotion regulation,altered motor function,and impaired drive. The default mode network(DMN),since it was first proposed in 2001,has become a central research theme in neuropsychiatric disorders,including schizophrenia. In this review,first we define the DMN and describe its functional activity,functional and anatomical connectivity,heritability,and inverse correlation with the task positive network. Second,we review empirical studies of the anatomical and functional DMN,and anti-correlation between DMN and the task positive network in schizophrenia. Finally,we review preliminary evidence about the relationship between antipsychotic medications and regulation of the DMN,review the role of DMN as a treatment biomarker for this disease,and consider the DMN effects of individualized therapies for schizophrenia. | Mao-Lin Hu Xiao-Fen Zong J.

| 3 | Outcomes of furazolidone-and amoxicillin-based quadruple therapy for Helicobacter pylori infection and predictors of failed eradication显示文摘AIM To evaluate the outcomes of furazolidone-and amoxicillin-based quadruple therapy for treatment of Helicobacter pylori(H. pylori) infection and identify predictors of failed eradication.METHODS Patients with H. pylori infection treated with furazolidone, amoxicillin, bismuth, and proton pump inhibitor therapy(January 2015 to December 2015) who received the ^(13)C-urea breath test > 4 wk after treatment were evaluated. Demographic and clinical data including prior H. pylori treatment attempts, medication adherence, alcohol and cigarette consumption during therapy, and treatment-related adverse events were recorded by reviewing medical records and telephone surveys. H. pylori eradication rates for overall and subgroups were evaluated. Multivariate analysis was performed to identify independent predictors of failed H. pylori eradication.RESULTS Of the 992 patients treated and retested for H. pylori infection, the overall eradication rate was 94.5% [95% confidence interval(CI): 94.1%-95.9%]. H. pylori eradication rate of primary therapy was 95.0%(95%CI: 93.5%-96.5%), while that of rescue therapy was 91.3%(95%CI: 86.8%-95.8%). Among the 859 patients who completed the study protocol, 144(17%) reported treatment-related adverse events including 24(3%) leading to premature discontinuation. On multivariate analysis, poor medication adherence [adjusted odds ratio(AOR) = 6.7, 95%CI: 2.8-15.8], two or more previous H. pylori treatments(AOR = 7.4, 95%CI: 2.2-24.9), alcohol consumption during therapy(AOR = 4.4, 95%CI: 1.5-12.3), and possibly smoking during therapy(AOR = 1.9, 95%CI: 0.9-4.3) were associated with failed H. pylori eradication. CONCLUSION Furazolidone-and amoxicillin-based quadruple therapy for H. pylori infection in an area with a high prevalence of clarithromycin resistance demonstrated high eradication rates as primary and rescue therapies with a favorable safety profile. Patient education targeting abstinence from alcohol during therapy and strict medication adherence may further optimize H. pylori eradication. | Ya-Wen Zhang Wei-Ling Hu Yuan Cai Wen-Fang Zheng Qin Du John J Kim John Y Kao Ning Dai Jian-Min Si | 2018 | World Journal of Gastroenterology2018,24,40: | 18 |

| 11 | Quantitative diffusion-weighted magnetic resonance enterography in ileal Crohn’s disease: A systematic analysis of intra and interobserver reproducibility显示文摘BACKGROUND Magnetic resonance enterography(MRE) is increasingly attractive as a noninvasive and radiation-free tool for assessing Crohn’s disease(CD). Diffusionweighted imaging(DWI) is recommended as an optional MRE sequence for CD by the European Society of Gastrointestinal and Abdominal Radiology, and has shown a superb potential as a quantitative modality for bowel inflammation evaluation. However, the measurement reproducibility of quantitative DWI analysis in MRE has not been ascertained so far. To facilitate the application of quantitative diffusion-weighted MRE in the clinical routine, systematic investigations of the intra and interobserver reproducibility of DWI quantitative parameters should be performed.AIM To evaluate the intra and interobserver reproducibility of quantitative analysis for diffusion-weighted MRE(DW-MRE) in ileal CD.METHODS Forty-four subjects(21 with CD and 23 control subjects) who underwent ileocolonoscopy and DW-MRE(b = 800 s/mm2) within one week were included.Two radiologists independently measured apparent diffusion coefficients(ADC)of the terminal ileum and signal intensity ratio(SR) of the terminal ileum to ipsilateral psoas muscle on DWI images(b = 800 s/mm2). Between-and withinreader agreements were assessed using intraclass correlation coefficients(ICC),coefficients of variation(CoV), and 95% limits of agreement of Bland-Altman plots(BA-LA LoA). Diagnostic performances of ADC and SR for identifying inflamed terminal ileum from the normal were evaluated by receiver operating characteristic(ROC) curve analysis.RESULTS There were no significant differences in ADC or SR values between the two sessions or between the two radiologists either in the CD or control group(paired t-test, P > 0.05). The intra and interobserver reproducibility of ADC(ICC: 0.952-0.984;CoV: 3.73-6.28%;BA-LA LoA: ±11.27% to ±15.88%) and SR(ICC: 0.969-0.989;CoV: 3.51%-4.64%;BA-LA LoA: ±10.62% to ±15.45%) was excellent for CD.Agreement of ADC measurements was slightly less in control subjects(ICC:0.641-0.736;CoV: 10.47%-11.43%;BA-LA LoA: ± 26.59% to ± 30.83%). SR of normal terminal ileum demonstrated high intra and interobserver reproducibility(ICC: 0.944-0.974;CoV: 3.73%-6.28%;BA-LA LoA: ± 18.58% to ± 24.43%). ADC and SR of two readers had outstanding diagnostic efficiencies(area under the ROC curve: 0.923-0.988).CONCLUSION Quantitative parameters derived from DW-MRE have good to excellent intra and interobserver agreements with high diagnostic accuracy, and can serve as robust and efficient quantitative biomarkers for CD evaluation. | Hao Yu Ya-Qi Shen Fang-Qin Tan Zi-Ling Zhou Zhen Li Dao-Yu Hu John N Morelli | 2019 | World Journal of Gastroenterology2019,25,27: | 7 |
| 12 | Human ACE2-Functionalized Gold“Virus-Trap”Nanostructures for Accurate Capture of SARS-CoV-2 and Single-Virus SERS Detection显示文摘The current COVID-19 pandemic urges the extremely sensitive and prompt detection of SARS-CoV-2 virus.Here,we present a Human Angiotensin-converting-enzyme 2(ACE2)-functionalized gold“virus traps”nanostructure as an extremely sensitive SERS biosensor,to selectively capture and rapidly detect S-protein expressed coronavirus,such as the current SARS-CoV-2 in the contaminated water,down to the single-virus level.Such a SERS sensor features extraordinary 106-fold virus enrichment originating from high-affinity of ACE2 with S protein as well as“virus-traps”composed of oblique gold nanoneedles,and 109-fold enhancement of Raman signals originating from multi-component SERS effects.Furthermore,the identification standard of virus signals is established by machine-learning and identification techniques,resulting in an especially low detection limit of 80 copies mL^(−1) for the simulated contaminated water by SARS-CoV-2 virus with complex circumstance as short as 5 min,which is of great significance for achieving real-time monitoring and early warning of coronavirus.Moreover,here-developed method can be used to establish the identification standard for future unknown coronavirus,and immediately enable extremely sensitive and rapid detection of novel virus. | Yong Yang Yusi Peng Chenglong Lin Li Long Jingying Hu Jun He Hui Zeng Zhengren Huang Zhi-Yuan Li Masaki Tanemura Jianlin Shi John R.Lombardi Xiaoying Luo | 2021 | Nano-Micro Letters2021,13,7: | 6 |

| 16 | A hierarchical indexing strategy for optimizing Apache Spark with HDFS to efficiently query big geospatial raster data显示文摘Earth observations and model simulations are generating big multidimensional array-based raster data.However,it is difficult to efficiently query these big raster data due to the inconsistency among the geospatial raster data model,distributed physical data storage model,and the data pipeline in distributed computing frameworks.To efficiently process big geospatial data,this paper proposes a three-layer hierarchical indexing strategy to optimize Apache Spark with Hadoop Distributed File System(HDFS)from the following aspects:(1)improve I/O efficiency by adopting the chunking data structure;(2)keep the workload balance and high data locality by building the global index(k-d tree);(3)enable Spark and HDFS to natively support geospatial raster data formats(e.g.,HDF4,NetCDF4,GeoTiff)by building the local index(hash table);(4)index the in-memory data to further improve geospatial data queries;(5)develop a data repartition strategy to tune the query parallelism while keeping high data locality.The above strategies are implemented by developing the customized RDDs,and evaluated by comparing the performance with that of Spark SQL and SciSpark.The proposed indexing strategy can be applied to other distributed frameworks or cloud-based computing systems to natively support big geospatial data query with high efficiency. | Fei Hu Chaowei Yang Yongyao Jiang Yun Li Weiwei Song Daniel Q.Duffy John L.Schnase Tsengdar Lee | 2020 | International Journal of Digital Earth2020,13,3: | 4 |
| 17 | Surveying brain tumor heterogeneity by single-cell RNA-sequencing of multi-sector biopsies显示文摘Brain tumors are among the most challenging human tumors for which the mechanisms driving progression and heterogeneity remain poorly understood.We combined single-cell RNA-seq with multi-sector biopsies to sample and analyze single-cell expression profiles of gliomas from 13 Chinese patients.After classifying individual cells;we generated a spatial and temporal landscape of glioma that revealed the patterns of invasion between the different sub-regions of gliomas.We also used single-cell inferred copy number variations and pseudotime trajectories to inform on the crucial branches that dominate tumor progression.The dynamic cell components of the multi-region biopsy analysis allowed us to spatially deconvolute with unprecedented accuracy the transcriptomic features of the core and those of the periphery of glioma at single-cell level.Through this rich and geographically detailed dataset,we were also able to characterize and construct the chemokine and chemokine receptor interactions that exist among different tumor and non-tumor cells.This study provides the first spatial-level analysis of the cellular states that characterize human gliomas.It also presents an initial molecular map of the cross-talks between glioma cells and the surrounding microenvironment with single-cell resolution. | Kai Yu Yuqiong Hu Fan Wu Qiufang Guo Zenghui Qian Waner Hu Jing Chen Kuanyu Wang Xiaoying Fan Xinglong Wu John EJ Rasko Xiaolong Fan Antonio lavarone Tao Jiang Fuchou Tang Xiao-Dong Su | 2020 | National Science Review2020,7,8: | 4 |
| 18 | Framework of behavioral indicators evaluating TB health promotion outcomes: a modified Delphi study of TB policymakers and health workers显示文摘Background:Although TB health promotion directed at policy makers and healthcare workers(HCWs)is considered important to tuberculosis(TB)control,no indicators currently assess the impact of such promotional activities.This article is the second in a series of papers that seek to establish a framework of behavioral indicators for outcome evaluation of TB health promotion,using the Delphi method.In the first article,we sought to establish a framework of behavioral indicators for outcome evaluation of TB health promotion among TB suspects and patients.The objective of this second article is to present an indicator framework that can be used to assess behavioral outcomes of TB health promotion directed at policy makers and HCWs.Methods:A two-round,modified Delphi method was used to establish the indicators.Sixteen experts who were knowledgeable and experienced in the field of TB control were consulted in Delphi surveys.A questionnaire was developed following 4 steps,and involved ranking indicators on a five-point Likert scale.The consensus level was 70%.Median,mode,and Coefficient of variation(CV)were used to describe expert responses.An authority coefficient(Cr)was used to assess the degree of each expert’s authority.Results:Consensus was achieved following the two survey rounds and several iterations among the experts.For TB health-promotion activities directed at policymakers,the experts reached consensus on 2 domains(“Resource inputs”and“Policymaking and monitoring behaviors”),4 subdomains(“Human resources”among others),and 13 indicators(“Human resources per 100,000 person”among others).For TB health-promotion activities directed at HCWs,the experts reached consensus on 5 domains(“Self-protective behaviors”among others),6 sub-domains(“Preventing infection”among others),and 15 indicators(“Average hours of daily workplace disinfection by ultraviolet radiation”among others).Conclusions:This study identified a conceptual framework of core behavioral indicators to evaluate TB health-promotion activities directed at policymakers and HCWs involved in TB control.Validation in other parts of the world could lead to global consensus on behavioral indicators to evaluate TB health promotion targeted at policymakers and HCWs. | Ying Li John Ehiri Daiyu Hu Eyal Oren Jia Cao | 2015 | Infectious Diseases of Poverty2015,4,1: | 4 |
| 19 | Scalable nanomanufacturing of surfactant-free carbon nanotube inks for spray coatings with high conductivity显示文摘Spray-coated carbon nanotube films offer a simple and printable solution for fabricating low cost, lightweight, and flexible thin-film electronics. However, current nanotube spray inks require either a disruptive surfactant or destructive surface functionalization to stabilize dispersions at the cost of the electrical properties of the deposited film. We demonstrate that high-purity few-walled carbon nanotubes may be stabilized in isopropanol after surface functionalization and that optimizing the ink stability dramatically enhances the conductivity of subsequent spray-coated thin films. We consequently report a surfactant-free carbon nanotube ink for spray-coated thin films with conductivities reaching 2,100 S/cm. Zeta-potential measurements, used to quantify the nanotube ink dispersion quality, directly demonstrate a positive correlation with the spray- coated film conductivity, which is the key metric for high-performance printed electronics. | Colin Preston Da Song Jaiqi Dai Zois Tsinas John Bavier John Cumings Vince Ballarotto Liangbing Hu | 2015 | Nano Research2015,8,7: | 4 |
